Which hair type is the most fragile and prone to damage?

Fine hair is known to be the most fragile and prone to damage among the different hair types. This is due to its smaller diameter and lower density of the hair shaft, making it more susceptible to breakage and damage from external factors like heat, chemicals, and mechanical stress. Fine hair often lacks the natural oils that help protect and nourish hair, leaving it vulnerable to dryness and brittleness.

Additionally, because of its delicate structure, fine hair can struggle to hold styles and may require gentler handling compared to thicker or coarser hair types, which tend to be more resilient. Understanding the unique characteristics of fine hair assists cosmetologists in recommending appropriate hair care products and techniques to maintain its health and appearance.
